A new approach with combination of fitting and encryption for transmission

Recently, since the wireless sensor network exhibits powerful performance, it has been frequently used in transmission of information in various fields. However, many problems are gradually revealed in the information transfer process. When wireless sensor networks transmit data packets for communication, the large amount of data makes the transmission very difficult. In the meantime, information is often intercepted or stolen by competitors that will cause data loss and leakage of important information. The study has resolved such information transmission problems successfully, high order polynomials is used to approximate data and transfer the simulation parameters, reduce the data transmission amount effectively and achieve better encryption effect. During the data transmission, the network simply transfers fitting parameters to reduce transmission amount. AES encryption mechanism is adopted in the process of parameter transmission to protect the data. Even competitors intercept data, it will still need to be decrypted. Assuming that competitors decrypt data successfully, they could only get the simulation parameters not the real data. Therefore, the scheme achieves the purpose of data protection. The advantage of this method is it avoids the large amount of data transmission and ensures the security and accuracy of the data. This data fitting method of encrypted transmission improves the wireless sensor network data transmission specifications and rationality, enhances the efficiency of data transmission and ensures the security and availability of data.
